Universal indicator toothpaste changes color based on the pH of the mouth. It can turn pink or red in an acidic environment and blue or green in a basic environment.
Universal indicator added to a toothpaste solution would likely turn a shade of blue or purple, indicating that the solution is basic due to the presence of substances like fluoride or calcium carbonate found in toothpaste.
Not to those that prefer a different hair colour.
It says on his official website red.
